Description
The S-Type PVC/PVC Thermocouple Compensating Cable is designed for economical transmission of S-Type thermocouple signals between the sensing point and temperature measurement instruments. Unlike extension-grade cables manufactured from the same noble-metal alloys as the thermocouple, compensating cables use specially selected substitute conductors that closely reproduce the thermoelectric characteristics of the S-Type thermocouple over a defined ambient temperature range. This significantly reduces installation costs while providing reliable signal transmission for industrial instrumentation systems operating within the cable’s specified temperature limits.
Manufactured in a 2-core, 24 SWG construction, the cable features PVC insulation and PVC outer sheath, providing good electrical insulation, flexibility, and mechanical protection for indoor industrial environments. Designed for ambient temperatures up to 105°C, it is suitable for connecting S-Type thermocouples to temperature controllers, PLCs, DCS systems, indicators, recorders, and industrial automation equipment.

FAQs
1. What is an S-Type PVC/PVC Compensating Cable?
An S-Type PVC/PVC Compensating Cable is designed to transmit the millivolt (mV) signal from an S-Type thermocouple to temperature controllers, PLCs, indicators, recorders, and other measuring instruments using specially selected compensating conductors that closely approximate the thermoelectric characteristics of the thermocouple within a specified ambient temperature range.
2. Why is a Compensating Cable used with S-Type Thermocouples?
S-Type Thermocouples use Platinum-Rhodium conductors, which are comparatively expensive. An S-Type Compensating Cable provides a more economical solution for transmitting thermocouple signals over suitable ambient temperature ranges while maintaining reliable measurement performance.
3. Why are S-Type Thermocouples used?
S-Type Thermocouples are widely used for high-temperature industrial processes requiring excellent measurement accuracy, outstanding long-term stability, and superior oxidation resistance. They are commonly used in furnaces, kilns, heat treatment, glass manufacturing, ceramic processing, and laboratory applications.
